[OpenIndiana-discuss] OI and chassis/jbod support?

[Dan Swartzendruber]

This is a bit annoying.  I am replacing two of the 600GB SATA drives (WDC)
with 1TB Seagate SAS drives.  diskmap.py finds neither of the 1TB SAS
drives, nor the 500GB SAS boot drive.  After much hair pulling, I discover
the problem is that sas2ircu and prtconf do not have the same serial number,
and not the '-' in the middle like diskmap.py tries to mangle.  example:

sas2ircu gives me Z1N1LX05 for one of the drives, whereas prtconf gives
Z1N1LX050000C2424AUR.  This seems to be true for all 3 SAS drives.  So the
hack I want to add to diskmap.py is to allow the leading string match, but
my python skills are 0 - having to learn this as I go :(

diskmap.py is a publicly available script written by someone else
whose name escapes me ATM which is useful for this.

I also have my own scripts which aren't in any state for anyone else
to look at ATM which do similar things.

/dev/es/ses??? will list SAS addresses for each slot; along with some other
stuff.
